This is a companion to the recent set-file-modes patch.
It adds support for a ‘nofollow’ flag to set-file-times (Bug#39773).
Like the set-file-modes patch, it needs work in the w32 port.
* admin/merge-gnulib (GNULIB_MODULES): Add futimens, utimensat.
Remove utimens.

When setting file times, avoid following symbolic links
when the file is not supposed to be a symbolic link.
* lib/futimens.c, lib/utimensat.c, m4/futimens.m4, m4/utimensat.m4:
New files, copied from Gnulib.
* lisp/gnus/gnus-cloud.el (gnus-cloud-replace-file):

* src/fileio.c (Fset_file_times):
Support an optional FLAG arg.
* src/fileio.c (Fcopy_file): Use futimens instead of set_file_times,
as it’s simpler and is a POSIX API.
* src/sysdep.c (set_file_times): Move from here ...
* src/w32.c (set_file_times): ... to here, and make it static,
since it is now used only in w32.c. Presumably w32.c should also
add support for futimens and utimensat (the POSIX APIs, which
Emacs now uses) and it can remove fdutimens (the Gnulib API,
which Emacs no longer uses).
* lisp/net/tramp-adb.el (tramp-adb-handle-file-local-copy): Do not use
'nofollow for temporary files. Use `tramp-compat-set-file-modes'.
(tramp-adb-handle-write-region): Do not use 'nofollow for
temporary files.
(tramp-adb-handle-set-file-modes): Implement FLAG.
* lisp/net/tramp-compat.el (tramp-compat-file-modes)

(tramp-do-copy-or-rename-file-directly)

* lisp/net/tramp.el (tramp-default-file-modes): Optional argument FLAG.
(tramp-handle-file-modes): Use `file-truename' instead of
`file-chase-links'. The latter function does not work for remote
file names.
(tramp-handle-write-region): Call `tramp-default-file-modes' with
'nofollow if needed. Do not use 'nofollow for temporary files.
* test/lisp/net/tramp-tests.el
(tramp--test-ignore-make-symbolic-link-error): Check also for
"Cannot chmod .* with nofollow flag" error.
(tramp-test20-file-modes): Extend test.
(tramp--test-emacs28-p): New defun.
This avoids some race conditions (Bug#39683). E.g., if some other
program changes a file to a symlink between the time Emacs creates
the file and the time it changes the file’s permissions, using the
new flag prevents Emacs from inadvertently changing the
permissions of a victim in some completely unrelated directory.

Functionally split tramp-loaddefs.el into two parts: one part run
while loading it at the very beginning of loading tramp.el (holding plain
autoloads and declarations), and another run at the very end of loading
tramp.el (holding setup code).
This should reduce infinite-recursion problems while loading.
* lisp/net/tramp.el: Require tramp-loaddefs at beginning.
Run (new and internal) tramp--startup-hook at the end.
Remove all tramp-autoloads. Prefer tramp--with-startup over
eval-after-load.
(tramp--with-startup): New macro.

error message.
(tramp-syntax-values): Explicitly return 'values'.
